Cadahia, Luis; Labra, Antonieta; Knudsen, Endre; Nilsson, Anna; Lampe, Helene M.; Slagsvold, Tore; Stenseth, Nils Christian (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)In migratory birds, mistimed arrival might have negative consequences for individual fitness, causing population declines. This may happen if arrival time is not synchronized with breeding time, especially when earlier ...

Motes-Rodrigo, Alba; Labra, Antonieta; Lampe, Helene M. (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)In songbirds, the development of the species‐specific adult song involves a learning process that varies in extension. In species that incorporate new song elements throughout life (open‐ended learners), variation in male ...

Ruiz-Monachesi, Mario R.; Labra, Antonieta (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Individuals of many species utter distress calls when are attacked or trapped by a predator. These vocalizations can help them to escape but may also help conspecifics to reduce their predation risk, by inducing antipredator ...

Fong, LJM; Navea, Fernando; Labra, Antonieta (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract For a prey, its best ticket to stay alive is to get early and accurate information on predation risk and so, escape from predation at low cost. Some prey species have evolved the ability to eavesdrop signals ...

Reyes, Claudio; Labra, Antonieta (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Los lagartos dependen principalmente de señales químicas y visuales para comunicarse y, en menor medida, de señales acústicas, por lo que en general se ha considerado que estos reptiles no emiten sonidos. Sin embargo, ...

Díaz, Sebastián; Labra, Antonieta (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Lizards, except geckos, are generally considered voiceless organisms, although some species emit oral sounds. For most of these “vocal lizards”, however, there is almost no information on the characteristics of the sounds, ...

Rojas, Valentina; Labra, Antonieta; Valdés, José Luis; Velásquez, Nelson A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Among amphibians, conspecific chemical communication has been widely studied in Caudata. Adult anurans, by contrast, have received less attention. Recently, it was shown that chemical scents are also relevant for adult ...

Labra, Antonieta; Reyes-Olivares, Claudio; Moreno-Gómez, Felipe N.; Velásquez, Nelson A.; Penna, Mario; Delano, Paul H.; Narins, Peter M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Effective communication requires a match among signal characteristics, environmental conditions, and receptor tuning and decoding. The degree of matching, however, can vary, among others due to different selective pressures ...

Reyes-Olivares, Claudio; Guajardo-Santibáñez, Andrés; Segura, Bernardo; Zañartu, Nicolás; Penna, Mario; Labra, Antonieta (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Vertebrate predation by invertebrates has been classically underexplored and thus underestimated, despite the fact that many arthropods consume vertebrates. To shed some light on the relevance that spider predation may ...

Fong, Lydia J. M.; Labra, Antonieta; Lampe, Helene M. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Few studies on song learning have been conducted in the field. Male pied flycatchers (Ficedula hypoleuca) seem to learn song syllables in the breeding grounds. Adult males arrive first to the breeding grounds and sing more ...

Ebensperger, Luis A.; Aspillaga-Cid, Antonia; Labra, Antonieta (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Background Previous bibliometric studies in scientific researchers from developed countries generally support that sharing efforts during research enhances productivity and impact and suggest these effects ...
-
Mora, Marta; Bardi, Francisca; Labra, Antonieta (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Globally, at least 43% of amphibian species are declining, due primarily to habitat destruction and modification, over-exploitation, emerging diseases, and invasive alien species. In Chile there are 60 species of amphibians ...

Troncoso-Palacios, Jaime; de Gamboa, Margarita Ruiz; Langstroth, Roberto; Ortiz, Juan Carlos; Labra, Antonieta (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In his recent self-published book "Reptiles en Chile", Diego Demangel Miranda presented 13 taxonomic changes for liolaemid and tropidurid lizards. While these could be considered validly published according to the International ...
